Markus said just a short report before heading off to work: nice sigs this morning from Laurie (137773.82 / 773.71) and Peter (773.09), both at equal strength within a dB or so. G3AQC's call was appa

Stefan, My stable/accurate time reference (GPSDO) should arrive in two weeks; in the meantime I am hoping to use 11904.76190 Hz (per your suggestion, thanks) to assess my soundcard clock frequency of

Stefan, Thank you for the help, I&#8217;ve made your suggested adjustments to the FFT setting settings. Today I plan to add a second axis to the VLF RX antenna; hoping that steering the antenna (RDF

Wolf, Thank you for the information. I opened the link that you provided and read most of the document; this is a big help. I am in the early stages of familiarizing with the Spectrum Lab manual, and

Hello Jim, Yes, this is the signal. They do not send a continuous tone but "beeps", thus the sidebands. You need to chance the FFT settings. First, "complex with internal frequency shift", centered t

Hello Jim, Stefan, and all, Jim's screenshot definitely shows the 'Alpha' (RSDN) signal. It's often difficult to tell which of the lines is the theoretic 'center' frequency - depending on how the var
